I used Supercharge Army Camp (uncommon) and it only took 15 hours to cool down. Not complaining but the card says "Usable once every 24 hours". I'm playing Old Town and have all the tech, but I don't see anything that would mess with the time.

I have no idea what happened.

The latest update changed active artifact cool downs to 16 hours. Sounds like the card text didn't keep up.

A recent update reduced the cooldown to 18 hours iirc (cant check from phone, will post correction later if im wrong), but that doesnt explain the other -3 hours

maybe fizzer change the cooldown time some more?

That is amazing.

Ah, it was 16 hours, my bad (thanks Danger)

@Fizzer pls make edit button for mobile, I really really need it...

i've noticed that on each of those artifacts it will show one hour less than expected but the actual activation time will be right.

example, 7:00 pm i click the button and 7:01 it will say 15 hours (really 15:59:00 hours) but it will correctly activate 16 hours after 7pm
